A car is a Muggle device powered by petrol, to transport one or more people. It is a very popular mode of transportation for Muggles, and it is known to have been used by wizards on some occasions. Although a car is defined as a Muggle artefact, and is therefore illegal to enchant under wizarding British law, nevertheless there are a few enchanted cars in Britain. The Ministry of Magic has cars that navigate traffic with magical ease. Mundungus Fletcher "borrowed" a car to take the Weasleys to visit Arthur in the hospital on Christmasday; he had magically enlarged it to fit more passengers. Ronald Weasley and Harry Potter were known to own one of these in their adult years.

Some Muggles viewed cars as status symbols and Vernon Dursley in particular tended to judge people by what type of car they drove. Harry Potter, however, felt that Vernon wouldn't have taken to Arthur Weasley even if he drove a Ferrari (a brand of car known for top-of-the line luxury.)

Despite generally showing disinterest or even disdain towards Muggle artefacts, many wizards are known to be envious of Muggles for their cars, and even staunchly anti-Muggle pure-bloods have been known to purchase luxury cars such as Rolls Royces.[2]
